Quickly import reference data sets for navigation system design and testing.

Project description

Organic Navigation Reference Data

The purpose of the onvadata module is to make reference data sets easily accessible for the design, development, and testing of navigation algorithms. The defining characteristic of reference data sets are that they are well understood, documented, and purged of data logging artifacts.

Quick Start

List Data Available

All data sets are referenced using their shortname.

>> import onavdata
>> onavdata.print_shortnames()
	 2011 UMN-UAV GPSFASER1
	 2012 UMN-UAV FASER5
	 2012 UMN-UAV GPSFASER3
	 2012 UMN-UAV THOR79
	 2012 UMN-UAV THOR77
	 2012 UMN-UAV THOR75
	 2012 UMN-UAV THOR60
	 SIM-PERFECT-CAR NORTH VARY-SPEED FIXED-HEADING
	 SIM-MEASURED-CAR NORTH VARY-SPEED FIXED-HEADING
	 SIM-PERFECT-CAR NORTH VARY-SPEED VARY-HEADING
	 SIM-MEASURED-CAR NORTH VARY-SPEED VARY-HEADING
	 SIM-PERFECT-CAR NORTH FIXED-SPEED VARY-HEADING
	 SIM-MEASURED-CAR NORTH FIXED-SPEED VARY-HEADING
	 SIM-PERFECT-CAR NORTH FIXED-SPEED FIXED-HEADING
	 SIM-MEASURED-CAR NORTH FIXED-SPEED FIXED-HEADING

Load a Reference Data Set

An abitrary data set can be loaded if no shortname is specified. In this case the data from 2014 UMN-UAV THOR77 was returned.

>> import onavdata
>> df = onavdata.get_data()
	get_data(): No shortname specified so choice will be arbitrary.  Returning: 2014 UMN-UAV THOR77
>> df.head()
